Follow these general guidelines when designing
the power supply:
- The power supply should be designed to provide
the operating conditions outlined in the
recommended operating conditions section in terms
of DC voltage, AC noise, and start-up ramp
time.
- The DS160PR822 does not require any special power
supply filtering, such as ferrite beads, provided
that the recommended operating conditions are met.
Only standard supply decoupling is required.
Typical supply decoupling consists of a 0.1 µF
capacitor per VCC pin, one 1.0 µF bulk capacitor
per device, and one 10 µF bulk capacitor per power
bus that delivers power to one or more devices.
The local decoupling (0.1 µF) capacitors must be
connected as close to the VCC pins as possible and
with minimal path to the device ground pad.
- The DS160PR822 voltage regulator output pins require
decoupling caps of 0.1 µF near each pins. The
regulator is only for internal use. Do not use to
provide power to any external component.
